Objections have been raised to a train that doesn't run underground through wealthy peninsula communities, including Palo Alto, Atherton and Menlo Park.

The Peninsula Cities Consortium is campaigning for a tunnel, with CHSRA saying that while expensive, the tunnel is being seriously considered.

Residents are mostly worried about their precious property values being affected by a fast train cutting through town, though one would imagine might actually go up with access to such a fast and convenient mode of transportation nearby.
